Question

Catron evaluates the expression (-9)(2 2/5 using the steps below

Answer 1

The answer is "-21.6".

Explanation:

In the given question, there is a mistype in the equation so, its correct equation can be defined as follows:

Given:

`\to (-9) (2 \ and \ 2/5) = (-9)(2+ (2)/(5))`

`= (-9 * 2 )+ (-9* (2)/(5))\\\\= (-18 )+ ( -(18)/(5))\\\\= -18 -(18)/(5)\\\\= (-90-18)/(5)\\\\= - (108)/(5)\\\\=- 21.6`

OR

`\to (-9)(2+ (2)/(5))= (-9) ((10+2)/(5))`

`= (-9) ((12)/(5))\\\\= (-9) (2.4)\\\\=-21.6`
